Method for Producing Monosized Ceramic Particle Through Organometallic Swollen Latex Particles

Abstract: 

Monosized ceramic particles produced through synergistic combination of monosized latex particles and organometallic reagents in a solvent system. By swelling a poly(vinyltoluene) or other monosized latex with an appropriate organometallic reagent, decomposing the organometallic to ceramic within the latex vehicle, and then removing the latex polymer through thermolysis, monosized ceramic particles are produced. The swelling of the monosized latex particles with the organometallic reagent requires the judicious selection of a solvent system specific to the latex polymer and organic being employed.
